Looks like we're talking about in-game here, where everything works, so...
Edit: Well, there went the pictures... Pokemon White was Smuglord, Doryuuzu, Dryad, the Water Ghost, Afro Tauros, and Wargle. Pokemon Black was unicorn otter, Ground/Dark Kremling, the coffin, Nattorei, and the levitating lamprey for sure, but I don't remember the other.
The alternates included Electric Zebra, Denchura, the Psychic ectoplasm Pokemon (though I forgot it couldn't be caught in Black), the deer, and I
think Chillachino and the Psychic/Flying that isn't Kokomori. Could be wrong. I don't even know what the other two were.
Pokemon White (JP), Team コレット
If Heart Scales are common enough, swap the least effective of those Pokemon for this:
Pokemon Black (JP), Team みのりん
The White team is pretty set in stone as my favorite designs this gen, but the Black team only has two of my favorite designs and mostly just features Pokemon who I think are pretty good (the deer isn't one of them) and who fit my style, so if any of them don't appear until very late in the game, I might just swap in any of the ones below. Otherwise I'll save them for my English copies or just not use them:
I'd also use this if it was catchable in Pokemon Black, but I'll just save it for my English copy of White:
